Reflection Instances To Get A List Of Applications Running
Jun 18, 2009
I have created a simple windows forms application. I would like to be able to connect to that running application and view certain properties from a seperate windows form application. In VB6 I would have run the first application and then called GetObject to connect to the instance. Does anybody know how I could do this in .Net. I'm guessing I'd have to use reflection to get a list of applications running and then somehow connect to them but I'm not sure how to do this?
Anybody have an idea to list running programs ; not all running background process. I tried following code, but which list all process names. eg: notepad.exe, vb6.exe, svhost.exe etc. but what i need is the running window based programs( with windows.)
1st method Dim process As Object For Each process In GetObject("winmgmts:").execquery("Select * from Win32_Process") Debug.Print process.Caption
I am currently writing an application in VB.NET that draws to a Microstation(MS) CAD application. Like Excel, MS has a robust COM object library that can be programed remotely. Hence, I am posting this in the VB Office Automation forum.In the case where the user invokes my program and there are multiple instances of Microstation(MS) open, I need to let the user determine which MS application instance they would like the program to draw to. It could be potentially catastrophic if the program draws to an unintended application/file.So my problem is this, I need to know how to convert an instance of the application that was found by enumerating through the GetProcessByName method in the Process Class, to an "Micros tationDGN. Application" object.I have read the responses to Post 1317219 by jprg. In a response to that Post, (Post 1317389) Mike_R replied;But if you want to actually manipulate the Excel instance via automation in order to create and save a new file, etc., then it's pretty close to impossible to convert an instance that you grab within via the Process class to an Excel.Application instance.
I'm looping all the properties in an object via reflection:
For Each p As PropertyInfo In values.[GetType]().GetProperties() If p.CanRead Then 'Do stuff End If Next
how to determine whether the property in question is a generic List(Of T)? If it is I need to loop the list itself.
I've experimented with GetType and TypeOf but have not managed to get anything working.
To clarify, I want to keep this generic. I do not want to specify the type of T, I need to loop the list items and call the ToString method on each item. T could be one of a number of different types (application specific reference types). Is it possible to do this without specifying types?
Running into problems creating objects through reflection and then running them on multiple threads.
I just cannot seem to figure out what I need to here:
For Each WorkerNode As XmlNode In oRunSettings.GetWorkerValues orkerName = WorkerNode.Attributes(SETTING_NAME_ID).Value Dim oWorkerType As Type = Type.GetType(String.Format("Worker.{0}", sWorkerName)) Dim oWorker As Object = Activator.CreateInstance(oWorkerType)
[Code]...
It is causing errors at the "AddressOf" because Object does not have a method called that. Do I need to do something with an interface?
I made a simple "restarter" app... However, I need to close multiple instances of an application. For example, if I have three windows of paint, or three windows of Word open, how do I check if it is still open before I open a new instance?
Is there a way to, when a parent application is opened up, that at the click of a button, or anything of designated event, that this parent application can open a secondary one?
How can I get all of the running applications? If I have to use Process.GetProcesses, then how can I determine which are applications (appear in the task bar)?
i am having trouble executing applications that havent got the prefix .exe here is the code tat i mostly found in the internet can someone help so it will be able to play with all applications tried to make it play with msi but it wont play.
I'm going to design an Application (C# or VB.NET) which use .NET Framework to run for very long time. It may be restarted every year or even more...Is there anything (using special design patterns or so) which I must care about in designing "Long time running applications in .NET"?
I developed an application I need to run exclusivly under DOS mode (no Windows), when I wrote the app I created it as a CONSOLE application, when I run this EXE under the DOS mode it says it can't RUN in DOS mode? Is there ANYWAY I can make this work?
I have seen that unsigned .net applications will not run on most college networks and as part of a school applications i am trying to let these applications run on a protected network. The app is written in VB 2008 and is signed strongly.
I have created an application that will run several other Engineering applications from within it.
I have my main form which will have a button on it for each application that has to be run. All the other projects are complete and have their respective '.EXE' files, which I have added to the main project.
I have coded one of the buttons to start an application, this is as follows;
Private Sub btnCoordsCalc_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCoordsCalc.Click Process.Start(My.Computer.FileSystem.CurrentDirectory & "Hole_Coordinates_Calculator.exe") End Sub
This method works OK and does start the application. So my question is; Is this the correct way to do it, or should I import the whole project into my main project?
i am a casual user of visual basic express 2008 and use Vista Home Edition Ive been using it for a while now, with no problems at all. Recently i started to take a look a WPF in my apps, again no problems.(visual basic express ran fine, debugging ran fine & finished apps ran fine)
However for some reason (and all of a sudden) i keep getting errors and none of my apps will start up. The errors are:vshost.exe has stopped working (I get this when visual basic express starts)PresentationFontCache.exe has stopped working (I get this when visual basic express starts a wpf app) (Application Name) has stopped working (I get this when running finnished apps)I've tried all the usual methods (Reninstalled VBE & .Net3.5)I cant see why it has stopped working all of a sudden?
he lack of VB terminology in the following question - this is all fairly new to me. Anyway, on to my question.I have 2 seperate applications running and they both need to access the same array. Is it possible? If so, how?
I have created a main application form that has buttons that start up various other applications.
Following advice on here from a previous post, I have imported all the files of each separate application into the main application.
There will be times when the user wants to run more than one of these applications at the same time. I know you can just import the '.EXE' file of each app, and you can then run several at a time. But because I have all the files without the .EXE, you can only run one at a time, you have to close one app to start another.
My question is simply; Do I have to import the .EXE file of each app, or is there some code I could put in my main form that will allow me to run more than one app at a time? (the reason for having all the files of each app is so you can make any alterations without having to open each app separately).
The code below is a typical code for one of the applications start buttons, all the buttons codes are the same, apart from the app name, the buttons are imported, so not standard buttons.
Private Sub btnCoordsCalc_ClickButtonArea(ByVal Sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles btnCoordsCalc.ClickButtonArea Dim frm As New frmHoleCoordinateCalculator
I am creating a dynamic clone method to be used in my custom classes. I want the clone function to be completely generic, so I do not have to make any changes when I add new properties to the class. I am having an issue with regards to making a deep copy a property that is a List. sample code that will enable me to identify with reflection that a property of my class is a List, and then more importantly the code to loop through the the List elements and copy of each of them. I have been able to identify a property as a List by using the NameSpace of the property type, but I'm not a big fan of that method. Either way, I have yet been able to dynamically loop and deep copy the elements of the property that's a List using reflection.
I'd like to ask assistance for the following scenarios below:
1. I want to check whether certain applications are already running or not. 2. The applications i need to check are the ff: a. MS Word b. MS Excel c. Notepad d. MS Project e. MS Powerpoint
3. If any of these are running, the window title of that application will be filled-in in a listbox.
I am running a client-server application and am having problems with privileges (I assume). The application is developed using 2005 Express. The Client is running Win XP Home whilst the server is running Win 2003. When the user on the client has Admin rights on the local machine, everything is OK; however when the user has only User rights, an error occurs: VB will not run.
I am wondering if it is possible to run an application from a domain account that has restrictions on running .exe files by coding in the local administrator details (username / password).
i would like to scan all the processes(aplications) running in a system before starting my program. and also need to close some programs before starting my program.how to read all the processes ruining in a system one by one.
I have a .NET class, InstrumentConnector, that has an event, StatusChanged. I want to create several instances of this class (each class handles a separate file) and respond when the StatusChanged event is raised any instance. How would I do this in .NET? Do I want to create a List(Of InstrumentConnector) or a similar IEnumerable? How do I write the event handler to respond to a particular instance's StatusChanged event?
Here is the InstrumentConnector class and the module with the StatusChanged handler:
Public Class InstrumentConnector Private _inProcessDir As String Private _doneDir As String
I would like to get a list of sql server instances on a computer but need both default and named instances.In the post: [URL] the code works perfectly for finding the default instance of SQL Server but it doesn't show other running instances (named instances). On my development computer, SQL Server Express, SQL Server 2005 (both named instances) and SQL Server 2008 (default) are all running but express and 2005 don't appear in the combobox dropdown list.
Using any version of .NET how do you find out which zone a particular share is classified under. I am having a problem identifying if a share where my referenced dlls reside is in the "intranet zone" or "internet" zone relative to some user machine that is running my .NET application. I suspect this is a problem because I am having a problem accessing referenced dlls from a share on some machines but not others. How can I tell which zone .NET is classifying that share in so I can adjust permissions accordingly?
Which is the best way to store application and user settings of an application running with multiple instances?My problem is that using the vb's "Application Settings" one instance would overwrite the other one.I want to identify each instance with a number passed via command line argument. I could use this number to identify the appropriate settings of the running instance, but I see in a local INI o XML file a better way to handle that.
I'm trying to figure out a way to sort the entries of a listbox... but in a different way instead of the obvious one (sorted property). First of all, I need to explain how the items are populated at first:
Is there a way to make long items wrap in a .net windows forms application, I have already got LabelWrap set to true, but it doesn't work, I am using Details View Type,
anyone knows the equivalent code for App.TaskVisible in VB.net? App.TaskVisible is from VB6 which hides the application in the applications list in task manager and not in the processes list tab.
